Davies has impressed Silva with his attitude so far, with the Portuguese boss even handing the youngster the captaincy on occasion.
The midfielder started in Everton’s final match before the international break, and helped Leicester City to a victory at the King Power Stadium.
But Silva insists that Davies needs to improve, if he wants to stay part of his starting line-up.
“For me, [the captaincy] is not the most important thing,” Silva said. “Tom performed well [against Leicester] because he is working hard.
“He feels the support from the technical staff and his teammates which they give to him. He is a boy - 20 years old - and he needs to improve.
“But he will improve and we are here to support him.”
Silva is clearly a big fan of Davies, as he has played him so regularly this term.
Davies has had some criticism at Goodison Park, but he still remains one of the brightest prospects in Everton’s team.
The Toffees’ win over Leicester before the international break was arguably their finest of the season, and gives them momentum to return to when the club action starts up again.
Everton are scheduled to play next in two weekends’ time, when they take on Crystal Palace at Goodison Park.
